As former Artistic Director of Celli@Berkeley and a San Francisco-based collective of cellists, Mosa commissioned and premiered new works for celli and electronics in the San Francisco Bay Area. In 2014, she co-produced Celli@Berkeley’s debut CD album in collaboration with composer Jared Redmond and Grammy-winning Barry Phillips. 

Mosa recently received her Master of Music from The Juilliard School. She holds bachelor's degrees in Music and in Society and Environment from UC Berkeley. Her honors thesis explored “Silence: In Performance and Within the Performer,” an analysis of the role of silence in music by J.S. Bach, Hans Werner Henze and John Cage.

Born to Taiwanese parents, she began playing cello at age seven in San Diego. Her past teachers include Joel Krosnick, Jonathan Koh, and Catherine Godden.

Mosa is the Regional Community Manager for Groupmuse in San Francisco. Prior to joining the startup, she presented 2 sold-out Massivemuses at a chocolate factory in Brooklyn and a co-working space in San Francisco. Her penchant for seeking interdisciplinary collaborations led to the San Francisco premiere of a work by Scott Rubin for 8 cellos and dancer controlling live electronics with motion sensors.

Mosa has performed 90 groupmuses in the San Francisco Bay Area and New York.

The most prolific groupmuser in our history. And she’s now, officially, a coast-to-coast Massivemuse impresario.

Mosa produced concerts for Celli@Berkeley, a 12-piece cello ensemble, at the Berkeley Art Museum. In 2016, she launched Celloscape, a collective of 14 cellists and composers dedicated to premiering new works for the cello. The debut concert, held at Bruce Beasley's Sculpture Studio in Oakland, was sponsored by Mrs. Laurence Beasley, Jennifer Howard, Marco Rozzano, and Linda Barnett.

Mosa is co-founder and U.S. Executive Director of Versoi Ensemble, a collaboration between Finnish and American musicians from the joint orchestra tour of Juilliard and Sibelius Academy students. Versoi Ensemble debuted at the United Nations, Kaufman Center’s Merkin Hall in New York and Holley Hall in Sarasota, Florida in November 2018.

As an arts administrator, she has contributed to Marlboro Music Festival, American Composers Orchestra, and International Contemporary Ensemble. Mosa serves as a fundraising consultant for emerging artists and new projects.
